In the wake significant caribou wastage late last month along the Tibbitt to Contwoyto winter road, there is another instance of what appears to be wastage related to ptarmigan. Yellowknife resident Brad Olson shared a social media post earlier this month showing what appears to be almost two dozen birds killed and left to rot.

On the Yukon River, subsistence salmon fishing is being closed to protect king salmon as they migrate upriver.

Since the initial June to July heatwave shocked the Pacific Northwest, Heim says the Tsolum River Restoration Society has observed significantly fewer fish in the river, especially in its lower portions. Many of the remaining coho, which survived the heat wave, are suffering from diseases and fin rot as a result of heat stress.

They are brightly coloured, beautiful and hungry — tropical fish and sea urchins are thriving in southern waters warmed by climate change. But now they are devastating kelp forests already knocked around by marine heatwaves.   

It's not the first time snow geese have died in large numbers in western Nunavut. The cause of this event is under investigation, but overpopulation could have played a role, says the Canadian Wildlife Service.

Thirteen of the state's 14 confirmed mammal deaths have occurred in the past month.

Late last month, the carcasses of a dozen or more caribou were found along the Tibbitt to Contwoyto winter road by someone who said the slaughter and wastage was an act of disrespect and greed.
